TANK-HEATER.

I Specification of Iietters Patent. "'1 p Patented 1c, 1916.

Application filed April 13, 1915. Serial nit-21,087. I

T 0 all whom it may concern Be it known that I, LEWIS V. FELDMAN, a citizen of the' United States, residing at Trosky, in the county of Pipestone and State of Minnesota, have invented a new and useful Tank-Heater, of which the following is a specification. y Y

The present invention appertains to a tank heater, and more particularly to a device adapted to be submerged in the water contained in a tank, trough or other recep.

tacle, and designed for heating the water, the device being intended for heating the drinking water supplied to farm stock although it may be employed for other purposes as well. i

The object of the invention isthe pro: vision of a tank heater. of novel and improved construction, whereby it will'eflectively serve its intended purpose, the present device having improved featuresof construction to enhance the utility and etliciency thereof.

It is also within the scope of the invention to provide a tank heater having the above mentioned features, and which is comparatively simple and inexpensive in construction, as well as being convenient, serviceable and practical in use.

\Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the com bination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The inventionis illustrated in the accompanying drawing, wherein Figure 1 is a vertical section of the improved heater. Fig. 2 is a plan view thereof, the cover and burner being removed. Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1, portions being broken away.

In carrying out the invention, there is provided an upright casing 1, having an angularly projecting extension 2 .at its lower end, the casing 1 and its extension 2 having a common bottom. That wall, designated 3, of the casing 1 adjacent the extension 2 projects downwardly below the top of the extension to provide an apron 0r partition 4 between the chambers within the casing 1 and itsiextension 2, and the apron 4 terminates above thesbottom of the casing to es tablish communication between the lower portions of the casing and extension chamers.

Transverse fiues 5 are terminally secured through the sides of the extension 2 imme-,

diately below the top of the extension, and above the horizontal "plane in ;which the lower edge of the apron or partition 4 lies, and an upwardly project-ing'discharge pipe 6 is attached to the extension 2 adjacent its top and projects to a point adjacent or above the upper end of the, casing r 1 l The upper end offthe casing l ispr'ovided with a hinged ,capor cover 7, which has a central raised portion 8 jprovidedin its side walls or periphery-with apertures or open.- ings 9, and an annular damper 10 is mounted for rotation upon the-raised portion 8, and is provided with apertures or openings 11 adapted to be brought into and out of registration withthe apertures 9. w

;...An.air inlet pipe 12 extends. upwardly within the casing 1 adjacent the wall 3 thereof, and its upper end passes through the cover or cap 7 while its lower end is extended angularly along the bottom of thecasing to a point centrally of the extension 2, as at 13.

The numeral14 designates the gasolene or 'kerosene burner, which is carried by the lower angularly extending arm 15 of the vertical gasolene or fuel pipe 16 which is connected at its upper end to the fuel tank or reservoir 17 The pipe 16 preferably extends through one wall of the casing.

In use, the casing 1 and its extension 2 are submerged in the water contained in the tank, trough or other receptacle 1S, and are held submerged upon the bottom of the tank or trough in any suitable manner. The casing 1 extends above the level of the water, and the water cannot therefore enter the casing or its extension, although the wateris free to flow through the fiues 5 and around the casing and its extension. 7 Theburner 14 maybe readily moved downwardly within the casing and may then be swung or moved under the apron 4 into the extension 2 below the fiues 5. The burner 14 being ignited or lighted, will heat the fines 5 and water conthen flow upwardlyout of the fines, which will draw cooler water into the flues which tained therein, and. the heated water will will in turn be heated by the burner. The water is thus effectively and quickly heated, and furthermore, the air within the extension and casing will be heated and the water adjacent the casing and extension will thus receive heat from the heated air within the casing and extension. Fresh air enters the pipe 12 and is supplied to or underneath the burner 14: by the lower angularly extending discharge portion 13 of the air pipe 12, whereby the combustion is supported, and the products 01" combustion will pass up wardly around the lines 5 and out through the discharge pipe 6. The cover or cap 7 closes the upper end of the casing 1, but the damper 10 may be controlled for either opening or closing the apertures 9, for purpose of ventilation.

It is evident that the products of combustion are confined within the upper portion of the extension 2 by means of the apron or partition 4, whereby the fines 5 will be properly heated by the flames and heated gases, and the apron 4 will reduce to a minimum, the liability or the products of combustion passing directly upward Within the casing 1 from the burner which would deprive the fines 5 of considerable heat.

From the foregoing, taken in connection with the drawing, it is believed that the advantages and capabilities of the invention are obvious to those skilled in the art, and will suggest themselves.

Having thus described the invention, what is claimed as new is Ina device of the character described, an upright casing having an angularly projecting extension at its lower end, and a depending apron'between the chambers Within the casing and extension, water circulating fines engaged through the sides of said extension above the plane of the lower edge of said apron, the extension being adapted to hold a burner below said fines, a discharge pipe projecting upwardly from the upper portion of said extension, a downwardly projecting fresh air pipe within the casing extended to a point within the lower portion of said extension, a cover for the upper end of the casing having a raised portion provided with apertures in its side walls, and an annular damper rotatable upon said raised portion and having apertures to be brought into and out of registration with the aforesaid apertures.

In testimony that I claim the foregoing as my own, 1 have hereto affixed my signature in the presence of two witnesses.
